Between having the airbox off multiple times and PO doing some slightly dodgy things, some of the threads for the airbox lid are now stripped. Has anyone experienced this, and what did you do to fix the problem?

(Not sure it is leaking, but possible connection to my poor running condition)

 

I have had a couple of them strip before. Most likely from the previous owner screwing them down so tight, they strip (not sure why they think they have to do this). With a plastic welder, I have melted plastic into the screw hole and it has worked fantastic. But, if you have a soldering iron, you can do the same thing. Melt the plastic around the top of the hole and kind of push the melted plastic into the screw hole. This does work.

 

Yes, same here, so i installed brass threaded inserts

 

Did you just drill to a particular size and loctite the inserts in? I had only considered putting bigger screws in. The beauty of a forum community hey?!

Would be cool to pour melted plastic in Crux, although I would need plastic, and a vessel to heat it and pour it. Mmm, project for next winter perhaps....

 

I stripped one and used Plastex for the repair. It was easy. See PLASTEX PLASTIC REPAIR KITS

 

seems weird, but I use this, as it is very easy to maintain and does the job. For the three bolts on forward I will use thread inserts, when the plastic will get ruined.

 

Drill hole, press in and forget it.

 

I use plastex on hard plastics like fairings.
But the softer stuff like the air box that will see frequent removal and install of the fastener I prefer to use thread inserts.
